Boiler Repairs
Boiler Repairs & Breakdowns Across Swansea, Neath & Carmarthenshire
No heating, no hot water, or a boiler that keeps locking out — we diagnose domestic boiler faults and carry out the repair. Based locally, so you are not waiting days for a national call centre to send someone.
Fault finding, not guesswork
Boiler faults can come from the boiler itself, the controls, the pump, the diverter valve or the system around it. We test in a logical order and use the boiler's own fault codes alongside our instruments, so the part we replace is the part that has actually failed.
That approach saves you paying for components your boiler did not need.
Common breakdowns we see
Loss of pressure, hot water but no heating, heating but no hot water, ignition faults, lockouts, noisy operation and leaking components are common on older boilers.
Some are quick fixes. Others mean a component is at the end of its life. We will tell you which, plainly.
Repair or replace?
If a repair is straightforward and the boiler is otherwise sound, repairing is usually the sensible option. If the boiler is old, inefficient or has repeated faults, we will explain the case for replacement honestly — including what it involves — without pressure.
Either way, you get a clear explanation before deciding.

Frequently asked questions
My boiler keeps losing pressure — is that serious?
It usually means a leak somewhere in the system or a failed component inside the boiler. Topping it up repeatedly only masks the problem, so it is worth investigating properly.
Can you repair a boiler that another company installed?
Yes. We repair domestic boilers regardless of who installed them, provided parts are available for the model.
